ROAD-BED.

Seriall No. 533,258.

To all whomY it. may concern;

Be ity known that. l, JOHN lileDerirorr, citizen of the United Sintes, residing at Dubuque, in the county of Dubuque and State of Iowa, have invented certain new and useful lniproyeinents in Road-Beds, of which the following is a specification.

My invention has relation to railways, with special reference to the beds of milways sind the object is to provide ii hed that will sustain the rails in the suine horizontal plane and furnish n sniooh siii-ieee .for the travel of the cars.

Another object is to furnish n ieiins whereby the expansion :intl conti-fiction of the mils and rail. hed will he provided for and still maintain a smooth surface for the ruil, also to (lo away with :i portion of the usuiiltios and still maintain u substantiel rond hed.

Another object. is to so anchor the heil that there will heno langer of spreading of the'raelr, rovide iiiil ties may he end'l still another object is to hed. with which any kind o used.

En what it consists, the mode of construc- -tion sind the meihier of operation will'he fully sei: out` in-the following specification when taken in-eonneetion with the, drawings accompanying the suine and forming u part. hereof. v

Figure l is ey plan view of the bed. Fig. 2 is ii cross section on line of Fig. 1 and showing :i rail Secured on the hed. Fig. 3 is a on. Fig. 4 ie n. perspective view showing one mode of attaching the hed to a tie. Fig. 5 is a perspective view of a loop for holdin;- Fig. G isn. side View of :i detail. A

Like charac-tere of reference denote corrosponding partis in eanh of the gures.

Referring to the dmwings. .2 represents n/seetion of the rail hed which consists of :i

metal plate 4 a trie wider-than the base of n railroad rail. Along one upper and outer edge runs va. 4hooked or bent flange 5 and along the o posite edge 4is another thing@ se of strengthening for c-ircu tion of the g Slate 4 und provi preventing niet, the harige 5 und the rib 6 is `'de elevation with a rail thei-eetneen the plate und ruil und thereby late 4 between the i provided with coi'- r: 'rations or ribs One end of er cli section is 'ined into :i rectangular shaped inten lowing hook l0, the other end of the section is formed into :ringer catch 12 adapted to he engaged hy interlock heel; if) und hold um seetions together. 'These Sections thus ionized together :ire fastened upon the ties. This iii-a3' he done by spikes 14 driven through the plate into the ties or hy n loop 15 shown in Fig. 5 pausing 'diagonally underneath the tie and held hy nuns i6. The spikes 14 muy no'he used especially where this rail plate if he used in repniring u rail ed.

For the pui'poee of preventing the plates i'runi spreading apart and the 4rails thereon there are provided stays 18 which consist ui :i metal har provided with a lugr 20 which pin projects up through a hole @ugh the. plete und the rib 6 and is seed hy e nul'. The mil muy he spiked n through the pluie into 'the tie in the iinairy wey or by crowding the ruil under For the purpose of strengthening the ruil also preventing eriy side movement of e e "und hed the rail hed may have a rib 7 running along mentwith the interf-lringf hook l0 und is spiked to the tie, l in this nimmer the entire rail hed is nl on one side. Then the other side of :he iwiil hed is iiliiced upon the ties and the i i l l l l l :ters 1S nre inserted in the rail bed first 'nifl ...in secured thereto, and since the stay is -if exact distance between the plates hut it is desired to have the rail separated, he stay is also secured to the other section, and the sections are then leid in the same manner that the first sections were laid. This quickly completes the laying of the ruil hed, but if the plates are to he held by the loop 15 then these may he attuched ne shown in Fig. 4; withthe loog: down bemeenten Apr. 43. 195i..

' i hook 5 and fastening the opposite Side neath the tie and provided with the nuts 1G ri idly holding the plate on the ties.

- n order to lay the rail 30 upon t'hc'plate It; 1s raised up at one edge and is inserted ruiter the hooked flange 5 and the other is pressed down and just enuages the rib t?.

Then the spikes are driven into thc ties on the side 6 or there may. be holes through the hooked flange 5 and the staples driven through those engaging the base of the rail. It will be seen by "this mode of constructing the rail bed that there need be far less number of ties as the plate .sections are inade of metal and are exceedingly Sirone. Another feature is thatif a tie should become loosened and inell'cetivo there. would be no danger of the displacement of the car from the track as the rail bed plate would be sutlicient to carry the train successfully over. There would -be a strain all along the entire track which would distribute. the weight ot' the cars unifmmliY and suiicicntly yielding to always hold the. rail in a horizontal plane, and hence the car would travel upon the track very sxnoothl)r without much jar. It will also be seen that. it would require very little to keep the rail bed in repair after it is once constructed, and the laying of the ails would be comparatively of small cxpense, and a greatl saving in ties.

Having new described my invention what I claim and desire to secure by Letters lat.- ent. is:-

1. In a device of the class described and in combination with railroad ties and car rails, a rail bed Formed in sections: means for uniting the sections together including lugs on the end of one section adapted to be engaged by interlocking hooks oi. a contiguous end of another section to form a continuous rail bed, and means connected with the rail bed for securing the rails upon the rail bed.

2. In a device of the class described and in combination with road ties and. car rails, a rail bed formed in sections and provided with a flange along one edge. and a rib along the opposite edge, means for uniting said sections together consisting ot lugs upon one end ot' the s-cction adapted to be engaged b v interlocking hooks on the ends of the contiguous section to form a continuous and unbroken rail bed, means for securing said rail bed to the ties, and means for curing the rails upon the rail bed between the [lange and the rib.
